Abstract (en)
A method of producing a cleaning cloth having abrasive properties is disclosed. The method comprises passing a composite material consisting of a needle bonded fabric, a woven or knitted fabric and a layer of foamed synthetic plastics material past a heat source which is preferably a gas flame. The gas flame is directed at the stitches of the exposed face of the needle bonded fabric and the layer of knitted or woven fabric is sandwiched between the needle bonded fabric and the layer of foamed material. The stitches of the fabric form hard, abrasive nodules the arrangement of which varies with the stitch pattern.
